The main objective of this research was to investigate the association between electroencephalogram (EEG) and memory recall in human participant. A sample of 34 healthy participants was recruited and exposed to 10 minutes animated learning contents. After 30 minutes of the learning session, they performed a memory recall task; the correct and incorrect responses in recall task were recorded for computing...
Recent research reveal that the Working Memory (WM) is more powerful than IQ as a predictor of academic success. However, there are factors that may influence WM performance, such as Attention. Although the impact of attention is well documented using ERPs; yet, the underlying brain connectivity of the interaction of these two constructs is not sufficiently understood. In this study, a Delay-Response...
Electroencephalography is most common noninvasive neuroimaging modality and it is widely used for measuring brain electrical signals. Measurement of electrical signals from the scalp requires high density electrodes and low noise amplifier. It is well known fact that neural activity increased with increasing the mental work e.g., IQ task in our case. In this paper, non-linear features have been used...
Multimodal neuroimaging techniques have shown better understanding of human brain functions and dysfunctions as compared to the standalone modality. EEG and fMRI are widely used in neuroscience community. EEG signals recorded at scalp have high temporal resolution and poor spatial resolution due to limited number of electrodes. Functional Magnetic Resonance Imaging (fMRI) has a very high spatial resolution...
The current study investigates the effect of distracted-driving based on EEG coherence. Forty-two non-professional drivers were recruited to perform a distracted driving task while 128-EEG channels of EEG were simultaneously recorded. EEG coherence computed from 12 EEG electrode pairs based on 10–20 EEG international system, resulting in 66 connections for theta, alpha and beta frequency bands. Results...
Concurrent electroencephalograph (EEG) and functional magnetic resonance image (fMRI) led researchers to acquire neuronal activities in detail over the past few decades. Regardless of the advantages of combining these modalities, artifacts posed a greater challenge to attain good quality data. One such problematic artifact which contaminates EEG recordings is Ballistocardiogram (BCG) artifact. A reference-free...
Functional Magnetic Resonance Imaging (fMRI) has very high spatial resolution as compared to the Electroencephalography (EEG) which on other hand has very high temporal resolution. The pros and cons of the EEG and fMRI are complementary to each other. Simultaneous EEG-fMRI data recording solve the problem to get high spatial and temporal resolution at the same time to study the brain dynamics in efficient...
In this research, we investigated the changes in brain dynamics with respect to playing video games on large screens. The large screen refers to a 40-inch display used in the experiment. Electroencephalography (EEG) data were recorded from the scalp while subjects played video games. A total of 14 male subjects participated in this study. EEG data was recorded for five minutes while the subjects did...
In this paper, we investigated the changes in brain activation with respect to watching movie clips in order to understand its effect on human brain. Electroencephalography (EEG) data was recorded using 24-channel EEG machine while subjects watched the movie clips. 14 male subjects were recruited for this research project. Two conditions were used in collecting EEG data; i) under eyes open condition...
In this research, we investigated the differences in brain activity while the subjects played video game. Experiment was conducted with two screen sizes; a large screen (40-inch display) and a small screen (3.5-inch handheld game). A total of 28 subjects participated in the study where two groups of 14 subjects played video games on two different screen sizes. Prior to video game play, baseline electroencephalogram...
